Shot Gun Dry Fire Machine

This machine was designed to dry cycle pump and semi-automatic shotguns for endurance testing of the trigger mechanism.  Every 5th cycle the force-distance data is collected for the entire stroke of the trigger utilizing an electric linear actuator with force and position feedback.  The data is stored in the PLC and is transferable via a network connection or USB flash drive.  A custom forestock clamp is used for each different gun and stock combination.  The buttstock is supported by an adjustable universal clamp.
